Hello. I have a 66 cutlass. To replace heater core I must out with heater box. Someone who can explain to me what I must do, preferably with pictures? I understand that it is difficult getting to some of the bolts, so would like some tips here. The car has a factory fitted AC :-)

No problem. There was just a few nutts that held the heaterbox. Removed it in just 30 min. Now its ready for paint and a new heater core :-)

If you jack up the car and support it correctly, then take the right front tire off and remove the right front inner fender this will make it much easier.

On a Cutlass, the heater core comes from under the dash. The nuts are on the firewall side. But the fender does not have to come off.
